Check Vehicle Fit

Dayco No Slack Automatic Belt Tensioners are specifically built to outperform and outlast competitive OE parts. The heavy duty cast aluminum spring case resists cracking and fatigue. Each component is built to resist rust, endure the toughest of conditions while promoting quieter performance and longer life.

Product Features:
  • Manufactured with a specially coated patented flat wire spring to allow the internal tension to be concentric, thus providing a more even degree of constant tension
  • Contains a metallic locator pin built to withstand extreme drive demands and properly locate the tensioner for installation
  • The patented Deflected Arm Plate dampens arm movement, prolonging the life of the tensioner by limiting the amount of rotational movement
  • This tensioner is another Dayco product proudly made in the USA

Quality seems good as other brands. 1998 Caravan. You may want to replace belt and idler pulley while doing this job, they seem to have a short life span due to design of vehicle. Install is not difficult, can be a little tricky. Best if you can raise front of vehicle and access nut from under and behind engine. Be safe, use drive on ramps, apply parking brake, shift trans to park and block rear wheels. You will need a couple of extensions and a swivel or wobbler as you can't get a straight shot at the mounting nut. May be able to remove alternator to access from top.

    I have bought two of these and am hearing the belt chirp again. Will only last about 35K before you'll have to replace. Spend the extra few bucks on a more quality tensioner.

        When trying to turn the tensioner to install the belt, the bolt stripped out of the tensioner. I had to rethread the tensioned and install a longer bolt. Bad design, should have been threaded all the way through with a longer bolt.

          I have a 95 Grand Voyager, 3.3 L. No way to remove from the topside. From under and behind the engine, you can see the nut holding the tensioner. If you're not too fat, you can reach, remove the nut with box end. Hard to place nut back on but I did. PTL Worked like a charm.

            1999 Chrysler Town & Country, 3.8L, ~151K miles. Replaced belt but still had belt noise. Replaced idler and tensioner together and the noise is gone (not sure which one was the problem). Still working fine after a week. Tensioner is easy to replace if you remove the nut on the back from under the van with 15mm socket and extensions with u-joint(s) or "wobblers" as needed to turn the corner.

                    For help with your project, I recommend purchasing a Haynes repair manueal specifically for your vehicle. This should be able to assist you further into detail on how to repair or replace specific parts.

                    A:

                    Yes, it could possibly be the tensioner. However, without the presence of your vehicle we would not be able to properly diagnose it nor provide you with a 100% answer. We would suggest taking your vehicle to a certified mechanic for a proper diagnosis before buying and having parts installed that may not solve or be the problem.

                    dorman makes a rain shield for the tension pully. Mine cost about 10.00 from the store.

                  • A:

                    Remove serpentine belt by using 15MM box-end wrench placed on
                    tensioner pulley nut and rotating clock-wise, remove belt from
                    nearest pulley, then release pressure on wrench. next, Jack-up passenger side of the van and set parking brake!! Crawl under vehicle with a flashlight and the shortest 15MM combination wrench you can find.Locate the 15MM nut on the back-side of
                    the tensioner and remove it. You can now remove the old tensioner from under the hood and install the new tensioner,
                    making sure to line up the small pin on the back-side of the tensioner with the recess on the mounting surface. Wedge something in front of the new tensioner to keep it in place, then crawl back under the van and install the 15MM nut on the
                    new tensioner stud/bolt then tighten to spec's. Reinstall belt and start van and check belt alignment.

                    Look for a diagram of the routing on the chassis of your car. There usually is one somewhere near the radiator.
